Even grizzly bears should watch what they eat. It turns out that grizzlies that gorge themselves on salmon during the summer spawning season have much higher levels of contaminants in their bodies than their cousins who rely more on berries, plants and insects, according to Peter Ross of Canada’s Department of Fisheries and Oceans.

Reporting in an article to be published Sept. 15 in the American Chemical Society journal, Environmental Science & Technology, Canadian researchers say

Scientists at the Naval Research Laboratory – Stennis Space Center (NRL-SSC) measured a record-size ocean wave when the eye of Hurricane Ivan passed over NRL moorings deployed last May in the Gulf of Mexico. The possibility of a super wave is often suggested by anecdotal evidence such as damage caused by Hurricane Ivan in September of 2004 to an offshore rig in the Gulf of Mexico that was nearly 80 feet above the ocean surface. Hence, some of the destruction done by Ivan has been attributed to

One in a new generation of computer climate models that include the effects of Earth’s carbon cycle indicates there are limits to the planet’s ability to absorb increased emissions of carbon dioxide.

If current production of carbon from fossil fuels continues unabated, by the end of the century the land and oceans will be less able to take up carbon than they are today, the model indicates.

“If we maintain our current course of fossil fuel emissions or accelerat

China’s rainy season has led to serious flooding in the north-east and south of the country. A joint Chinese-European team is gathering Envisat radar imagery of the developing situation to give the authorities a way to swiftly assess affected areas and plan their responses.

Summer flooding is nothing new in these regions of the People’s Republic of China (PRC), though this year it is proving particularly severe, with more than 800 casualties countrywide and 2.45 million peop

A colourful summer marine phytoplankton bloom fills much of the Baltic Sea in this Envisat image.

Phytoplankton are microscopic marine plants that drift on or near the surface of the sea, by far the most abundant type of life found in the ocean. Just like plants on land they employ green-pigmented chlorophyll for photosynthesis – the process of turning sunlight into chemical energy.

While individually microscopic, phytoplankton chlorophyll collectively tints the surrou

Being seasick is not a problem for scientists on a major expedition now under way in the middle of the Atlantic Ocean. That’s because most of the researchers investigating the eerie Lost City hydrothermal vent field are working “aboard” a landlocked science command center in Seattle.

Only four scientists are with University of Rhode Island oceanographer Bob Ballard aboard the Ronald H. Brown, a research vessel operated by the National Oceanic and Atmospheric Administrat
